5 Pcs Serial RS232 9 Pin Gender Female to Female Adapter Changer

These work good for their designed purpose. One thing to note is that if you need to remove the screws the metal housing will come apart. But that was ok for what I needed them for.

work great. I got these to connect my Honeywell Ademco VT-SERCBL to my Amphenol CS-DSDMDB09MM-015 9-Pin DB9 Deluxe... which then connects to my key-span USB to serial converter

BUYER BEWARE: These do not have the RX and TX lines crossed. We found this the hard way by manually crossing the receive/transmit lines on a pair of DB9 Female connectors to see if our unit worked. Turns out it did.For crossed RX/TX, see this: https://www.amazon.com/CablesOnline-Slimline-Transfer-Adapter-AD-N06M-2/dp/B00HGJD0L4/ref=pd_sim_147_4?ie=UTF8&psc=1&refRID=EACWRKAKXRA1TC3QZPX5

As described

The metal screw connectors blocked my pin. I had to take them off (which is easy). But the metal brackets around the blue plastic are not glued. They simply fell off.On the male / male gender bender - these outside metal pieces are clearly glued. Disappointed they skimped here. I had to glue the pieces myself (not entirely necessary).

Works great!

This product is advertised as a 9-pin to 9-pin adapter, however neither side fits any 9-pin in my office.

OK stuff

Die bestellten Teile waren in Ordnung und entsprachen der von mir erwarteten Qualität. Die Liefrung war pünktlich. Alles Bestens

Easy to use and very good materials

la descrizione del prodotto e' sbagliata.dovevano avere un lato maschio e uno femmina e come ogni prodduttore specifica quando vendo un prodotto del genere se vedo scritto maschi femmina mi aspetto di ricevere quello.invece sono femmina dai entrambi lati..

Im Demoeinsatz für die Verbindung von CAN-Bus-Kommunikationsboxen. Ist dafür nicht gedacht, erfüllt aber seinen Zweck vollständig.

Don't work. Plus the screws on the sides prevent plugging in to some serial plugs.
